40mm vs 44mm Apple Watch: Which one should you buy?

If you want the largest display size available in Apple Watch with greater battery life and you have your heart set on a leather loop band, then the 44mm Apple Watch is the right choice.

On the other hand, if you have a smaller wrist and want to don a modern buckle band or simply want to go with the least expensive Apple Watch, then a 40mm Apple Watch will suit your needs.

We recommend you try both versions at the Apple store to get the case size and screen feel. This will also let you know how the watch band looks on your hand. It is always better to test before purchasing an expensive gadget.
